Abstract: 762,637. Wall and like brackets. LARSEN, T. Aug. 5, 1954 [Aug. 7, 1953], No. 22794/54. Class 52 (5). In an ironing board &c. comprising a board member having, at one end, a bracket detachably mountable on a carrier member attached to a wall, and a supporting leg adjustable in length and secured to the board at a point spaced from the end carrying the bracket, the carrier member consists of a vertical rail having a longitudinal row of apertures to receive spaced hooks on the bracket. As shown, a bracket 11 screwed to the board 10 has spaced hooks 12, 13 engaging, with no lateral clearance, cross-shaped apertures 18 in a channel rail 14 welded to a sheet metal member 15 secured to a wall 17. Abutments 26 on the hooks engage the rear surface of the rail and, to prevent angular displacement of the board, the hooks may be spaced to engage non-adjacent apertures and clamping screws provided to abut the end surface of the board on the wall. A locking hook 25 is also provided. An arm 31 of an adjustable iron stand 30 is pivoted to the board and a telescopic supporting leg 19 having a non-slip ferrule 24 is pivotally mounted midway along the board and occupies the alternative positions shown in Fig. 2. In modifications the carrier rail is recessed into the wall and a work table for heavy loads has a U-shaped leg the limbs of which are individually adjustable in length.

Abstract: 1475788 Hair driers MITSUBISHI DENKI KK 22 May 1974 [28 May 1973 16 June 1973 (2) 20 Aug 1973] 22920/74 Heading A5R [Also in Division Fl] A hair drier comprises a main body 10 containing an electrical air blower unit, a flexible hose 48 connected to the air outlet of the blower unit, a tubular air outlet member 54 attached to the other end of the hose, and electrical air heating means in the outlet member, the latter consisting of a heatisolating sheath containing the heaters and a holder rotatable on the sheath, to form a heat-isolating space. The body 10 is lined with sound absorbing material 18 such as foamed polyurethane, and is divided by a partition 20 into a suction compartment 22 and a delivery compartment 24. Partition 20 has a central recess provided with a multiplicity of holes 27, and an electric blower 26 is fitted into the recess through a vibration absorbing rubber 28. Blower 26 has its delivey side supported by a plate 30 secured to opposite walls of body 10. Suction compartment 22 contains a suction port unit including a suction tube 38 having a bottom wall provided with a plurality of vent holes 40 and a layer 42 of porous sound absorbing material, serving as a dust filter. A delivery tube 44, covered by a dust filter 46, is connected to the inlet end of hose 48. Within outlet member 54 the heat-isolating sheath (64), Fig. 3 (not shown), encloses a bobbin (70) of cruciform cross-section helically wound with a length of coiled heating wire (72). Three flexible leads (74, 76, 78) are connected respectively to an end, to the centre and to the other end of the wire, and extend through hose 48 into body 10. Annular heat-isolating space (90) between the inner surface of the holder (80) and the outer surface of the sheath (64) communicates through holes (68) in the sheath with the inside of the hose. A portion of the air passed through hose 48 flows into the space (90), and to the outlet of member 54. When not in use member 54 may be inserted into suction tube 38 (as shown by dotted lines in Fig. 2) where it depresses an arm 100a to open a normally closed switch 100, so as to switch off the mains supply to the drier. Three switches (102, 104, 110) are provided in the electrical circuit, Fig. 4 (not shown), for respectively starting the blower, applying mains voltage to the full heater, and applying mains voltage to only half of the heater. In another embodiment, Fig. 5 (not shown), means for adjusting the quantity of air leaving through the delivery tube 44 consists of an adjustable aperture leading from delivery compartment 24 to a leakage opening (126). Various nozzle elements (92), Fig. 1 (not shown), or a comb (94) may be attached to the outlet member 54.

Title: Landing control system for aircraft
IPC: G05D1/06
Filed: 1970-05-13
Abstract: 1316485 Aircraft landing systems SPERRY RAND CORP 13 May 1970 [19 May 1969] 23074/70 Heading B7G [Also in Division G3] A landing control system for an aircraft has pitch control means 10, 11 and a flare computer 14 responsive to aircraft altitude and rate of descent and a parameter L which may be varied by means 21 prior to a flare initiation point determined by aircraft altitude to produce a pitch command signal which is connected to the pitch control means 10, 11 at the flare initiation point by a flare point detector 27. The flare computer 14 computes the pitch command signal in accordance with the equation Jh+ h + L = 0 where h is altitude, J is a nominal flare time constant and L is a nominal touchdown rate of descent. Values of h and h are obtained from a radio altimeter 15 and vertical accelerometer 17, and the term Jh is computed in a summing circuit 19 and fed to an amplifier 20 where it is combined with the term h and with L which is obtained from a bias network 21. The output from amplifier 20 is fed to a coupler output amplifier 22 and to an amplifier 25 where it is combined with a pitch up bias signal from source 24. Prior to flare initiation, as shown in Fig. 1, the output from amplifier 22 is fed back to its input through integrator 23, and at the flare initiation point switches 26, 29 are switched so that the output from amplifier 25 is fed to integrator 23 and the pitch command signal is fed to an automatic flight controller 10 or a flight director 11. The touchdown rate of descent L is varied prior to flare initiation in accordance with reference airspeed V REF  which is computed from values preset by the pilot or from aircraft weight and stall speed and fed to multiplier 37 through a sample and hold circuit 37<SP>1</SP>, which maintains the signal constant after flare initiation. The airspeed of the aircraft is maintained at V REF  during landing by a throttle control 12 or 12<SP>1</SP>. In another embodiment, Fig. 3 (not shown), J is varied in accordance with the flight path angle γ relative to the sustaining air mass, the latter being determined by the relation in a flight path angle computer (41), and fed to a multiplier (44) through a sample and hold circuit (43). In this embodiment L is computed as a function of V REF  and γ.

[Class 47 (ii).] An extinguisher 1 wherein the fusion of solder in case of fire allows a spring 12 to force a capsule 16 of compressed gas against a piercer 17, is closed at its upper end by a soldered closure la and is provided at its outlet end with a tube 8. The spring 12 operates against a slidable member 11 formed with a stem 10 which is secured to the tube 8 at its lower end by readily-fusible solder 13. The stem 10 passes through, and is soldered to, a disc 20 which is also soldered, at its periphery, to the outlet end of the vessel. The disc thus normally provides a hermetic seal for the vessel. When the solder 13 is fused by fire, the stem 10 disrupts the disc 20 and the capsule 16 is forced against the piercer. The liquid in the vessel 1 is then forced through apertures 9 in the tube 8 into the sprayer 3. As shown, the vessel 1 is enclosed in a casing 2 having at one end the sprayer 3 and at the other end a closing cap 4. A cap 6 of combustible material is mounted over the sprayer. The extinguishing liquid may be delivered by tubing to distant points, flame from such points being carried to the cap 6 by fuse cords.
